Why element selection drives interaction in Cypress - Test Execution Impact

Test Overview

This test checks that a button on a webpage can be found and clicked using Cypress. It verifies that selecting the correct element is essential to interact with it successfully.

Test Code - Cypress

Cypress

describe('Button click test', () => {
  it('should find and click the submit button', () => {
    cy.visit('https://example.com')
    cy.get('#submit-btn').click()
    cy.get('#message').should('contain', 'Success')
  })
})

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Cypress test runner is ready	-	PASS
2	Browser opens and navigates to https://example.com	Page loads with a submit button and message area	-	PASS
3	Find element with id 'submit-btn' using cy.get('#submit-btn')	Submit button element is located	Element with id 'submit-btn' exists	PASS
4	Click the submit button using .click()	Button is clicked, triggering page action	-	PASS
5	Find element with id 'message' and check it contains text 'Success'	Message element shows 'Success' text	Assert message contains 'Success'	PASS

Failure Scenario

Failing Condition: The element with id 'submit-btn' is not found on the page

Execution Trace Quiz - 3 Questions

What is the first step Cypress takes to interact with the button?

A Find the button element using cy.get('#submit-btn')

B Click the button directly without finding it

C Check the message text before clicking

D Reload the page

Key Result

Selecting the correct element is crucial because all interactions depend on finding that element first. If the selector is wrong, the test cannot proceed to click or verify anything.
